The manufacturing method
of butyl titanate
1. Introduction

Butyl titanate is an important chemical production raw material, widely used in coatings, plastics, rubber, ceramics and other fields. Due to its unique physical and chemical properties, the manufacturing method of butyl titanate has attracted much attention. This paper will introduce the manufacturing method of butyl titanate in detail, including raw material preparation, reaction process, post-treatment and so on.

2. raw material preparation

the main raw materials for the manufacture of butyl titanate are tetrabutyl titanate and ethanol. Among them, tetrabutyl titanate is a colorless and transparent liquid with strong reactivity; ethanol is used as a solvent and a reactant. In the process of raw material preparation, it is necessary to ensure the purity and quality of raw materials to avoid adverse effects on subsequent reactions.

3. Reaction Process

The reaction process of manufacturing butyl titanate mainly includes the following steps:

1. adding tetrabutyl titanate and ethanol into a reactor according to a certain molar ratio, stirring and mixing evenly.

2 While stirring, a certain amount of water was gradually added dropwise to initiate a transesterification reaction. At this time, the temperature in the reactor gradually increases.

3. Control the reaction temperature to avoid excessive temperature to cause side reactions. At the same time, stirring was continued to allow the reaction to proceed sufficiently.

4. After the reaction is completed, the reactor is cooled to precipitate a solid product, butyl titanate.

4. post-treatment
After the
reaction is completed, the product needs to be post-treated to obtain a higher purity butyl titanate. The specific post-treatment steps are as follows:

1. Pour the mixture in the reactor into a centrifuge, and perform solid-liquid separation to obtain a crude product of butyl titanate.

2 The crude product is washed to remove impurities and by-products. Generally, ethanol and water are alternately washed.

3. After washing, the butyl titanate is dried in vacuum to obtain a product with high purity.
Precautions for
5.

In the process of manufacturing butyl titanate, the following matters need to be paid attention to:

1. Control the reaction temperature to avoid excessive temperature causing side reactions and affecting product quality.

2. Ensure the purity and quality of raw materials to avoid adverse effects on the reaction.

3. In the post-processing process, the product needs to be fully washed and dried to ensure product quality.

6. conclusion

tetrabutyl titanate as an important raw material for chemical production has broad application prospects. By mastering its manufacturing method, the effective production and quality control of butyl titanate can be realized, which provides support for the development of related fields.
